I just finished downloading and Id like to verify the integrity of my download like this:

import os
import subprocess
import requests

# Read the list of URLs from v1_6.txt
with open("dolma/urls/v1_6.txt", "r") as file:
    urls = file.read().splitlines()

# Extract the filenames from the URLs
expected_files = [url.split("/")[-1] for url in urls]

# Get the list of downloaded files using ls -lh command
ls_output = subprocess.check_output("ls -lh /home/markusheimerl/xvit-415020_dolma/", shell=True).decode().strip()
downloaded_files = [line.split()[-1] for line in ls_output.split("\n")]

# Find missing files
missing_files = set(expected_files) - set(downloaded_files)

# Print the missing files
if missing_files:
    print("Missing files:")
    for file in missing_files:
        print(file)
else:
    print("All files have been downloaded.")

# Verify the integrity of downloaded files
print("\nVerifying file integrity:")
for url in urls:
    filename = url.split("/")[-1]
    if filename in downloaded_files:
        response = requests.head(url)
        expected_size = response.headers["Content-Length"]
        local_size = os.path.getsize(f"/home/markusheimerl/xvit-415020_dolma/{filename}")
        
        if expected_size == local_size:
            print(f"{filename}: OK")
        else:
            print(f"{filename}: Mismatch (Expected: {expected_size} bytes, Local: {local_size} bytes)")

But response.headers["Content-Length"] throws a key error. Sure that has more to do with how cloudflare hosts those files but a separate textfile with all the file hashes provided by you would be great!
